vusun123 Posted April 2, 2015 Share Posted April 2, 2015 It's natively support. Don't inject anything with your bootloader Link to comment https://www.insanelymac.com/forum/topic/305367-radeon-hd-7770-xfx/#findComment-2124794 Share on other sites More sharing options...

vusun123 Posted April 3, 2015 Share Posted April 3, 2015 not exactly, I need running two monitors only recognizes the HDMI and without audio True, VGA isn't supported on 7770, maybe framebuffer patching is needed but AFAIK it only blackscreen-ed. HDMI Audio is achieved through DSDT patching and AppleHDA Link to comment https://www.insanelymac.com/forum/topic/305367-radeon-hd-7770-xfx/#findComment-2125024 Share on other sites More sharing options...
#McFly Posted April 6, 2015 Author Share Posted April 6, 2015 Thanks for your response Only with DVI-I works perfectly or just the HDMI also works perfectly Together does not work the DVI-I, is black screen, only the HDMI works Link to comment https://www.insanelymac.com/forum/topic/305367-radeon-hd-7770-xfx/#findComment-2125572 Share on other sites More sharing options...
